Rotwood Thallid

At the beginning of your upkeep, put a spore
counter on Rotwood Thallid.

Remove three spore counters from Rotwood Thallid: Create a 1/1 green Saproling creature token.

When Rotwood Thallid dies, search your library for
a noncreature artifact card with a mana cost less
than the number of spore counters on Rotwood
Thallid, put that artifact into play tapped, then
shuffle.
